In small bowl, with mixer on high speed, beat heavy cream and sour cream until stiff peaks form. With rubber spatula, gently fold cream mixture into white chocolate just until combined.

To serve, on each of 8 dessert plates, place 1 cookie; top with half of cream and fruit mixtures. Repeat layering. Top with remaining cookies; sprinkle with confectioners' sugar if you like. Garnish with strawberries.
